MICHAEL A. 'ZINNIEL, or FREE-PORT, MmuEsorAL 1 i WHEELBARROW.

Application filed July 14,

Z aZZ iv/tom it may 60mm;

Be it known that L MICHAEL A. ZINNIEL,

a citizen of the United States, residing at Freeport, in the county of Stearns, State of Minnesota, have lIlVGIltGCl certain new and T 1 .V 1 useful impi ovements in l ee oaiious, anc

' I do hereby declare the 1 following to be a full, clear, and exact description ofithe-invention, such as will enable others skilled in the art to which it appertains to make and use the same. V This invention relates to new and useful improvements in wheel barrows, and has for its primary object to provide a device of this character which is operable to discharge the load carried thereby.

A further. object of the invention is to provide a device of this character in which the bottom of the wheel barrow is adapted to automatically deposit the material sup ported thereby under the influence of the weight of said material.

A further object of the invention is to provide novel .means vfor maintaining the body in its closed position against the action ottheweight of the material supported by said body. 7 t

Referring to the drawings v .Figure l is/a side elevation of the device in its dumping position,

Figure 2 is a transverse section on the lirie'2-2 of, Figure 1 with the device in its closed position, V Figure 3 a longitudinal section on the line 33 of Figure 2 showing the device in its closed position Figure 4 is a rear end elevation showing the position of the parts when the bottom is in closed position, I Figure '5 is a similar view showing the position of the parts when the device is in the dumping position,

Figure 6 is a bottom vice in closed position,

Figure 7 is a detail view of one of the plan view ofthe def bottom supportingboards, and

Figure 8 is a detail view of the forward transversely extending beam or frame member.

Referring more particularly to'the draw I ings, the device comprises a rectangular frame '10, the side members 11 of which are forward transversely extending brace 12, and a rear transverseh extending brace 13, each of said braces belng Specification of Letters Patent. v

spaced a suitable distance from the respective ends of the side members 11. Depend ing from the, ed eof the side members 11 near the rear en s thereof are legs 14, while the forward ends of the side members are provided with bearing blocks 15 in which is suitably mounted ahsha ftor the like 16 and secured to which are the spaced wheels 17. Projecting upwardly from the side members. are side boards18" vwhich are connected at theirends by end boardsforthe like '18 and19, the end board 1}) being movably' retained in place.

Rigidly secured to each ofthe side meinbers 11 of the frame'are brackets 20, there beingone pair ot'brackets for each side member 11, and supported in said brackets is a.'longitudinally extending shaft or the" like 21 Bottom boards 22 are provided on their under face with strap members 23, the. free endsofwhioh are bent around the longitudinal, shafts 21'- to provide means by which the bottom boards 22' are pivotally mounted on the sidemembers 11 of the rectan'gular frame.

versely, extending. brace 12 and depending from the under facefthereof is afpair of. spaced brackets 24, and connecting the leg members I I4, is a transversely extending brace 2 5,v the upper edge of which is pro,- vided with bearings 26; which latter are in longitudinal 'alinement with bearings 27 in .the' bracket 24.

members 28 and as; shown in Figure 3 these members are provided with a portion 29 which is adapted to'be received within the brackets 24. Extending from the bracket engaging portion 29 of each of the crank members is a right angular projection 30 and extending from said right angular projection 30 is a right angularvportion 31,

which lies in a plane parallel with its respective bottom board 22 and extends throughout the length of said bottom board. The crank member 28 is then'bent to form a right angular portion 32 from which pro-v jects'a right angular portion 33, which latter is adapted. for engagement within its re spective bearings 26 in thetransversely ex,- tending leg brace 25, and projecting from said right angular portion 33 is a right angular portion 34 which terminates in a right angular crank 35. It is to be understood that one of the members just described and illustrated in Fi re 3 of the drawings is employed for eac of the bottom boards 22, and is provided at a suitable point between its ends with rollers 36- which are adapted adaptedto engage one of the crank members'35', andsecured to the-transversely extending leg brace is a resilient clip 41, which is adaptedto engage said transverse member 38 to retain thesame in its lowest position to prevent opening of the bottom boar-(19221 I The operation ofthe device is as follows: Vith ;the' parts in the position shown in Figure 4 itwill' be seen that the bottom.

boards 22 of the body will be maintained in their closed position by reason of the transversemember 38 being secured a ainst vertical movement. in "the guides '37. I ith the parts in this position the bodyof the 7 wheel barrowmay bejfilled with any suitable material. When itis desired to dump the material from the body it isonly necessary to disengage the resilient clip 41 from the trans V verse member 38 whereupon the weight of therefrom} I H I M p From the'foregQing it will be seen that. r V, the present invention providesawheel barrow which m yb loadedwith material and transportedfrom place to place as desired, said wheel' barrow being capableof dis-V the material on the bottom boards 22 causes. them to rock-on their pivotal point to the position shown in Figure 5 where the material contained in the body is discharged charging the material at. the will. of the operator in a simple and easy manner.

Having thus described the invention, what is claimed is V 1. A dumping wheel barrow comprising a rectangular frame, supporting legs carried by the frame, a transversely extending brace connecting said legs, pivoted bottom boards secured to the side members of the rectangin. lar frame, and means pivotally mounted in the transversely extending leg brace and one of the transverse members of the frame and extending lOIlgltLlCllHEtllY of the said pivoted bottom boards for moving them to open and closed position.

2. Ajdumping'wheel barrow comprising a rectangular frame, legs depending from r the frame, bottom boards pivotally carried by the sides of the frame, and rockable crank shafts supported at one end in the a frame and at their other ends in'the trans versely extending legbrace and carrying rollers engaging the lower faces of said pivoted bottom boards to move, the same to open and closed position. Y A dumping wheel barrow comprising a frame,v a pair oft-hinged bottom boards carried by the sides of the frame, depending brackets carried by the forward end of the frame, a transverse bar supported below the rear of the frame longitudinal crank shafts having their ends. rotatably supported in the brackets and on the bar respectivel rollrs carried by the cranks .ofthe sha ts and engaging in supporting relationt'o the bot-I 7 tom boards and means for rocking thes'hafts to swing the crank portions toward the hinged portions of the bottoms to permit said bottoms to swing downwardly into dumping position. I i

In testimony whereof, I affix my signature, in the presenceof twowitnesses.
